The two classic methods
Avalanche pays the highest interest rate first. It minimizes total interest paid. Snowball pays the smallest balance first, regardless of rate. It produces faster wins and more momentum.
If you have $12,000 across four accounts at 29%, 24%, 9% and 0%, avalanche saves real money. If you have ever abandoned a budget in week three, snowball may save the plan itself.
A worked example
| Debt | Balance | APR | Minimum |
|---|---|---|---|
| Card A | $4,200 | 28% | $105 |
| Card B | $1,800 | 22% | $55 |
| Medical | $900 | 0% | $50 |
With an extra $300 per month, avalanche puts it toward Card A first and saves the most interest. Snowball clears the medical bill in three months, then rolls that payment into Card B. The snowball finish line feels closer; the avalanche finish line costs less.
The hybrid we usually recommend
- Make every minimum payment on time. This is non-negotiable.
- Build a small buffer — one paycheck, not six months — so a surprise does not become a new balance.
- Clear the smallest balance if you need a win, then switch to the highest rate.
- Automate the extra payment for the day after payday.
- Review every 90 days. A raise, a refund or a rate change should change the plan.
What matters more than the method
Consistency. A $300 extra payment every month for 24 months beats a $1,000 payment in month one followed by nothing. Automate it, make it boring, and do not re-open the cards you just paid off.
When the math says something harder
If the minimums exceed what you can pay after housing and food, a payoff method is not the right tool. That is the point to look at a debt management plan, a consolidation loan or a conversation with a licensed bankruptcy attorney. Getting honest early is cheaper than pretending for a year.
